Idiomatic in PL means "as intended by language authors", "according to idioms on which the language was designed". And because language authors usually know better how the language should work, idiomatic is good.

What does "idiomatic" mean? And why is it a good thing?

very compact

Hi,

It's doable, keeping the kata in draft and sending them the link. But they cannot "submit final" as long as the kata is in draft.

Note: CW isn't supposed to be used as support for courses. For pedagocical support, you should go with the Qualified version (but it's not free)

cheers

can I somehow publish Katas available only by direct link? I'm not sure I want to spend much time on supporting all the rules, but I only need Katas for my students basically

I see I need to add more tests... :D

too long... ;p

Nice 😎

and correct sentences in the description. I almost had to guess what the task was... :s

Same issues as your other one. Copy-pasting @B4B's comment from that one (see below).

If you're interested in authoring kata, I'd strongly suggest you read the links below first and then that you participate a bit to the beta process (solving beta) to see how it generally goes and what are the expectations.

• https://github.com/codewars/codewars.com/wiki/Kata-Creator
• https://github.com/codewars/codewars.com/wiki/Tutorial%3A-Create-Your-First-Kata

For instance, your kata is lacking:

• random tests
• novelty (there is a § about that in the links)
• proper testing: in this kind of kata, you have to do an extensive check for boundaries

Not to mention the incohesive nature of the conditions.

Writing a function to do the work of a builtin isn't very idiomatic though either.

shortest, but not idiomatic
